Mint Star - 4mm - Gilson Lab Opals

Our Mint opal stars are opaque and flash green, blue and sometimes a bit of yellow. The opals are flat on all sides and quite thin, so they are easy to encase. These opals do not require a special annealing cycle like the rough opals do. Just encase, keep warm in the kiln, and incorporate into your work.
